British concern about rapid increase in German naval power resulted in a costly building competition of ''
Dreadnought''-class ships. This tense arms race lasted until 1914, when the war broke out. After the war, a new arms race developed among the victorious Allies, which was temporarily ended by the Washington Naval Treaty.
In addition to the British and Germans, contemporaneous but smaller naval arms races also broke out between

Charles Glaser argues that numerous cases of arms races were suboptimal, as they entailed a waste of resources, damaged political relations, increased the probability of war, and hindered states in accomplishing their goals. However, arms races can be optimal for security-seeking states in situations when the offense-defense balance favors offense, when a declining state faces a rising adversary, and when advances in technology make existing weapons obsolete for the power that had an advantage in the existing weaponry.
Artificial intelligence arms race
A military artificial intelligence arms race is an arms race between two or more states to develop and deploy
lethal autonomous weapons systems (LAWS). Since the mid-2010s, many analysts have noted the emergence of such an arms race between global superpowers for better military AI,
driven by
increasing geopolitical and military tensions. An AI arms race is sometimes placed in the context of an
AI Cold War between the US and China.
Other uses
An
evolutionary arms race is a system where two populations are
evolving in order to continuously one-up members of the other population. This concept is related to the
Red Queen's Hypothesis, where two organisms co-evolve to overcome each other but each fails to progress relative to the other interactant.

More generically, the term is used to describe any competition where there is no absolute goal, only the relative goal of staying ahead of the other competitors in rank or knowledge. An arms race may also imply futility as the competitors spend a great deal of time and money, yet with neither side gaining an advantage over the other.
